To all whom it may concern:

Be it known that I, \VILLIAM Hovnv Ennmnns, citizen of the UnitedStates, residing at Leesburg, in the county of Loudoun and State ofVirginia, have invented certain new and useful Improvements inGrease-Gun-Filling Devices, of which the following is a specification.

ll his invention relates to improvements in filling. apparatus forgrease guns, the novel feature of which consists in the provision offilling means adapted for co6peration with devices of this character tofacilitate the operation of filling the same.

The primary object in view is the provision. of a simple filler deviceor apparatus which can be easily and cheaply manufactured for use withany of the well "known types of grease guns and consists essentially ofa cylindrical shell into which the semiliquid or solid lubricant isinitially ixitroduced by the aid of a coacting ladle member, said shellthen being inserted into the grease receptacle of substantiallycorresponding capacity to effect the transfer of said lubricant theretothrough the cooperation of the ladle member aforesaid.

To best understand the novel characteristics of this device it may bestated that it is commonly known to'those skilled in the art to whichthe invention refers that the filling of a grease gun to the extent ofits capacity is extremely diliicult, if not substantially impossible. sothat the operation of furnishing a motor or similar vehicle withlubricant of this character, such for example as supplying thedifferential or gear housings, is accomplished with much labor and. lossof time due to the fact that the. quantity capable of being introducedinto the gun at onetime is so small. More I specifically speaking, it iscustonmny. for instance, to remove the nozzle from one end of the barrelof a grease gun after retracting the plunger toward theother end andinsert small quantities. of the grease at a time, pressing the samedown. generally.

with a stick or similar article, but-by reason of the fact that the airescapes so slowly l from the barrel, it is practically impossible to getany quantity near the capac ty of the receptacle therein, or even whenthe an is allowed to pass out freely from the barrel of the grease onthe walls of the barrel is so considerable as to resist any materialfilling of the same. Furthermore, the use of a plunger member forforcing the grease downwardly becomes impractical because upon thewithdrawal of said member the grease is sucked outwardly therewith. Byactual experience I have also found that for various reasons to suckgrease into the gun by the plunger member provided for forcing ittherefrom, as is customary. results in drawing but a negligible quantityinto the same, due perhaps to the nature of the lubricant. It has alsobeen proposed to plunge the barrel of'a grease receptacle of thischaracter bodiiy into a bucket of grease but it is rare that the bucketcontains lubricant of a depth equivalent to the length of the garlandtherefore this is not feasible. To the end of overcoming thesediiliculties and disadvantages I have conceived of a simple device bywhich the grease initially placed into a shell-like filler member to thefull capacity of the same may be inserted into the grease receptacle andby introducing the ladle member hereinbefore mentioned into the fillermember said grease may be bodily transferred to the receptacle upon thewithdrawal of said filler In1lll)61'.

\Yith the above and other objects in view, this invention consists inthe construction, combination and arrangement of parts all ashereinafter more fully described, claimed and illustrated-in theaccpmpanying drawings, wherein-3 Figure l is a view elevation of agrease receptacle of the usual type and with such as my invention isdesigned to cooperate; Fig. 2 isa longitudinal sectional view showing myfiller device in cooperating position, and in 'dotted lines the shellelement partially withdrawn; Fig. 3 is an elevation of the shell memberalone; and Fig. t is a plan view of the ladle member.

'lhroughout the. following detail description. and on the severalfigures of the drawiugs, similar parts are referred to bylike referencecharacters.

Referring to the drawings, Fig. I illustrates a grease gun of theordinary type comprising the barrel or cylindrical receptacle 1 having athreaded plunger or piston 2 operable therein and passing through theknurled closure member 3 detachably connected to one end of the barrel.The other end of the barrel is likewise provided with a knurled closurecap 4 screwed thereon and to which is detachably connected the nozzle 5through which greaseis adapted to be forcibly ejected, by movement ofthe plunger 2 in the barrel, the usual operation of these devices. Forsuch I provide a cylindrical shaped or tubular shell 6 having at oneside a slot 7 extending longitudinally from one end of the same to theother. One end of this shell is bell-shaped or flared, as indicated at8, to facilitate manipulating the same, as will be more clearly setforth hereinafter. Into this shell, shown most clearly in Fig. 3,grease, known commercially as cup or journal grease, is introduced by aladle member 9, constructed similar to the embodiment shown in Fig. 4,which comprises the disk 9 adapted to be inserted into said shell, andthe actuating means or handle therefor, 9, which passes through the slot7 during the filling operation now to be more clearly described.

Having first retracted the plunger 2 of the gun and removed the nozzleand cap members from the same, the shell 6 is held in one hand,preferably placed over the smaller end, and grease is then pickedup bythe ladle member 9 by which it is pressed into the shell toward the handon the smaller end aforesaid, whereupon said ladle member is rotated soas to enable the disk to be withdrawn through the slot. As will beappreciated, this removal of the ladle member from the shell at anypoint in the length of the same serves that the grease is prevented frombeing withdrawn from the shell by suction in the action of retractingsaid member from the filling end. The thickness of the material of thedisk is, preferably slightly less than the width of the slot 7, ofcourse, and in the action of withdrawal of this member through the slotany of the grease adhering to its surfaces will be scraped off by theedges of said slot. The filling action just described is continued untilthe shell is quite full to its capacity, when it is inserted bodily intothe barrel 1 of the grease gun. The ladle member is then inserted on topof the grease in a position'hest shown in Fig. 2, and holding the'samerigidly in this position, the operator grasps the shell 6 about theflared end and withdraws the.

same entirely from the barrel, thus leaving the full quantity of greaseor contents of the shell therein which may then be ejected into themachine or other place of deposit a particular function in' purview ofthe use of my filler device thatthe same need not necessarily beinserted entirely within the grease receptacle since obviously thecontents of the shell might readily be forced therefrom if one end ofthe same were to be placed at the mouth or opening of a receptacle toreceive the grease,

when holding the ladle member on top of said grease by movement of saidmember downwardly in the slot. The relative action of the shell or ladlemember is obviously immaterial, that is to say, whetherthe shell memberis moved while the ladle meniber is held rigidly, or vice versa.

Having thus described my invention, what I claim as new is 1. A fillerdevice of the class described comprising a shell, arotatable fillermember operable in said shell for filling the same and moving thecontents therealong, and manipulative means for rotating the fillermember to permit withdrawal of the same away from the contentsintroduced into the shell thereby.

2. A filler device of, the class described comprising a shell, a ladlemember operable in said shell to fill the same, said member being of across sectional area substantially conforming to the cross section ofthe shell, and a handle member connected to the ladle member andoperable to rotate said ladle member to permit withdrawal of the sameaway from the contents and out of the shell.

3. The combination, with a receptacle for grease, of a shell adapted tobe inserted therein and having a 'slot. at one side, a rotatable memberoperable in the shell for transferring the contents of the same into thereceptacle aforesaid upon withdrawal of the shell therefrom, andactuating means for said rotatable member extending through the slot.

4. A filler device for grease guns comprising a hollow tubular memberhaving a slot at one side and a rotatable ladlemember operable in saidtubular member for filling the same, said ladle member comprisingactuating means extending througl the slot for manipulatingthe ladlemembe whereby the latter may be rotated int a position for withdrawal,of the sam through the slot.
